6 Claims.

This invention relates to loop pile fabric, and

has for an object to provide an improved type of loop forming the pile, wherein the separate threads making up the yarn from which the loops are made react differently to the application of moisture, as for instance, in dyeing.

A further object of the invention is to provide a loop pile fabric, the yarn of which is made up of threads of different properties which react differently to the application of moisture, whereby the finished product discloses upon the surface only one of the threads of the yarn, the other thread being positioned below the surface defined by the first mentioned thread.

A further object of the invention is to provide a yarn made up of animal and vegetable threads inter-twisted, which will react differently to the application of moisture, then weaving the intertwisted yarn into a pile fabric in the usual well- 0 known manner, and then dyeing in the piece whereby the animal and vegetable fibre threads are subjected to moisture and to react thereto in accordance with their nature, which differs one from the other.

i The invention, therefore, comprises the weaving of a loop pile fabric from a yarn made up of one thread of animal fibre and one thread of vegetable fibre, and dyeing the fabric after weaving, the vegetable fibre thread sinking downwardly relative to the loop, while the animal fibre thread extends upwardly relative to the vegetable fibre and in most cases twists upon itself.

In the drawing:- Figure 1 is a view in elevation of a yarn twisted from animal and vegetable fibre threads.

Figure 2. is a diagrammatic view showing the position of the threads after weaving in the usual manner for all pile fabrics, and

Figure 3 is a diagrammatic view showing-the 0 vegetable fibre thread depressed and widened, and the animal fibre thread upstanding and twisted upon itself.

Like characters of reference indicate corresponding parts throughout the several views.

In providing the yarn from which the pile fabric of the present invention is woven, animal and vegetable fibre threads are twisted loosely together. The animal thread may, by way of illustration, be mohair and the vegetable fibre thread 1 likewise referred to as cotton, without in any way limiting the invention to such combination or to either of the components.

At Figure 1 the thread is intended to represent the animal fibre thread while the thread 11 represents the vegetable fibre thread.

At Figure 2 is shown diagrammatically the Weave wherein the vegetable fibre thread 11 and the animal fibre thread 10 are formed into the loops 12. This is done upon any type of loom ordinarily. employed for weaving loop pile fabric and the invention is in no way limited to the manner of weaving.

There is also diagrammatically shown the threads 13 which represent the foundation. Of

course, all of these threads are warp threads and animal and vegetable fibre produces a different action of such fibre. For instance, the vegetable fibre 11 mats down and the loops are, consequently, lower than the animal fibre threads 10 which have a tendency to stand up and to twist 7 upon themselves, all of which is shown at Figure 3.

When the animal and vegetable fibres have been subjected to a bath which affects both similarly, it is obvious that they willappear in substantially the same color. However, they may be subjected to baths which affect only an animal fibre or a vegetable fibre, or to two baths of different colors, in which case the vegetable fibre which has matted down forms a background for the animal threads which stand up in pointed relation. This produces an effect quite different from anything heretofore accomplished by reason of the fact that the foundation is scarcely visible, but is obscured by the matted down vegetable threads.

Of course the loop pile fabric herein illustrated may be modified and changed in various ways without departing from the invention herein set forth and hereinafter claimed.

I claim:

1. A loop pile fabric having loops formed of a yarn composed of both vegetable and animal fibre threads, the vegetable fibre threads in each of said loops being matted down and the animal fibre threads therein standing more erect.

2. A loop pile fabric, each loop of which is constructed of yarn composed of threads of different material, one of which has a tendency to mat down and the other to stand up and twist, following the application of moisture thereto.

3. A loop pile fabric, each loop of which is composed of yarn made up of animal andvegetable threads, reacting differently to the application of moisture.

4. A loop pile fabric, each loop of which is composed of yarn made up of animal and vegetable 6. The method of producing a loop pile fabric consisting in forming a yarn of threads of animal and vegetable fibre respectively, weaving a loop pile fabric of said yarn, and dyeing the fabri'c whereby the vegetable fibre threads mat down and the animal fibre threads stand erect and twist.
